Lighter Tips, of which the following is a specification.

This invention aims to produce an improved electric cigar lighter tipwhich will be simple in construction and inexpensive to lt-further seeksto perfect a deused, and to this end proper insulationand anefiectiveguard for the heating element are installed. 7 t is a further obgect toconstruct a device which will satisfactorily withstand long andcontinued use.

With the above and other objects in View, 7

the invention comprises the construction and arrangement of parts aswill now be described and hereinafter specifically claimed.

' its center for the insertion of the end of the .guard to the circularportion.

the outer insulating disk and the circular guard 1s a ring 1 havingperforations at diametrically opposite sides thereof, through which areinserted the ends of a core or insulating material 18. On the core andadja' cent the ring are two insulating washers 19.

A wire 20, extending from the center contact, passes through aperforation in the inner insulating disk at or near its center, as shownat 21, thence it extends between the spaced apart insulating disks asshown at 22, thence it passes through a perforation in the outer portionof the outer disk, as shown at 23, and thence it is spirally wound onthe insulating core for approximately the dis- Specification of LettersPatent.

tance between the insulating washers, thus forming a resistance 0011 asshown at 24:.

The wire then passes back through the opposite outer portion of theouter insulating disk, as shown at25, between the disks for a shortdistance toward their centers, as shown at 26, through the inner disk,as shown at 27, and thence it is attached to the screw plug, as shown at28. The resistance coil, which is the heating element of the device,becomes white hot when the electric current is applied, by reason of theresist ance which it affords.

The guard is an efiectual protection against accidental burning by theheating element. The resistance coil has contact with insulating membersonly, that is, with the insulating core and the insulating washers. Thewire is insulated from the screw plug by the insulating button and theinsulating disks.

The insulating core may be made of porcelain or other suitable material.Porcelain will withstand a great amount of heat for long periods withoutlosing its shape.

li hat I claim is:

1. An electric cigar lighter tip, comprising a wire having a resistancecoil, an insulating core by which the coil is carried,

perforated ring carrying said core, a guard, a screw plug by whlch thelighter tip is carried, insulating washers on said core and interposedbetween said ring and coil, and

perforated insulating disks interposed between said coil and screw plug,whereby said wire may pass through said disks to form the contacts ofthe screw plug.

2. An electric cigar lighter tip, comprising an insulating core, a wirehaving a resistance coil on said core, a guard, a screw plug by whichthe lighter tip is carried, insulating washers protecting said coil fromsaid guard, and two spaced apart, perforated insulating disks protectingsaid coil from said screw plug, and the ends of said wire passingthrough perforations in outer portions of the outer of said disks,thence between said disks and toward each other for short distances,thence through spaced apart perforations in the inner of said disks, andthence to the screw plug, one end of said wire forming the centercontact and 'the other end constituting the side contact of said screwplug.

8. An electric cigar lighter tip, comprisso i ing a wire having aresistance coil, an insulating core by which the coil is carried, aguard for the resistance coil, means for insulating the guard from thecoil, a screw plug, and spaced apart insulating disks through whichthe'wire passes and by which the coil is insulated from the screw plug.

4. An electric cigar lighter tip, comprising an insulating core, a wirehaving a resistance coil carried thereby, a perforated ring carrying theinsulating core, a guard for the resistance coil, washers interposed"between the perforated ring and resistance coil for insulating the guardfrom the coil, and spaced apart insulating disks through which the wirepasses and by which the coil is insulated from a screw plug.

An electric cigar lighter tip, comprising an insulating core, a wirehaving a resistance coil carried thereby, a perforated ring carrying theinsulating core, a guard for the resistance coil, washers interposedbetween the perforated ring and resistance coil for insulating the guardfrom the coil, and two spaced apart, perforated insulating disksprotecting said coil from a screw plug, said perforated ring interposedbetween said guard and one of said disks, and the ends of said wirepassing through perforations in outer portions of the outer of saiddisks, thence between said disks and toward each other for shortdistances, thence through spaced apart perforations in the inner of saiddisks, and thence to said screw plug.

In testimony whereof I- affix my si nature.
